Strong showing for Labor in fresh Newspoll

Malcolm Turnbull's Coalition government has slipped to another low, now trailing Labor by eight points in the latest Newspoll.

The poll, published in The Australian on Monday, has the Coalition at 46 and Labor 54 per cent on a two-party preferred basis, while primary support for the government dropped from 37 to 36 per cent.

Labor's support remained steady at 38 per cent while both One Nation and the Greens remained steady at eight and nine per cent respectively.

Mr Turnbull also lost ground to Bill Shorten as preferred prime minister, his 42 per cent to Mr Shorten's 31 a four-point fall since the last poll.

Treasurer Scott Morrison would not be drawn on whether former prime minister Tony Abbott's discussion last week about crossing the floor on a clean energy target contributed to the result.

"What I know is we're in the middle of dealing with a lot of very important issues," Mr Morrison told ABC radio.

"I think as the results continue to come in on the good decisions we're making ... and when people start to see those over a longer period of time I think that's the time when we might see some change."
